For me this is about the definition. A pianist may have a disability if they loose a finger tip, for someone else this may not have a big impact on their life. Someone with a broken leg may be temporarily disabled.

I think "labels" can be helpful to a point, but for me, thinking I am "disabled" would mean not trying to make things better for myself, to lose hope. I do not want to be defined by that label. However accept for others, this may be helpful to them.
